I'm a fan of short boot times.  Are there that many users that are
power cycling their pc's frequently?  Of all the pc's I use be them
Windows or Linux, work or personal, hardly any of them are rebooted.
Really only my test boxes (which are intended) or in the event of a
power loss or so due to very bad weather.  Of course that's just my
usage and everybody has their own.  I just don't see that this is a
situation that's even remotely common.

I'm not for or against the idea.  I just wonder if there's significant
need to distract Klaus away from other things people have been
needing/wanting for quite a long time.
